Cards(player) size does not fit

[ozateck]

Hello everyone!!

I want to upload my game on my twitter…
But, I have some trouble on “Twitter Card (Player)”

So, I was checked on “CardValidator” like this…
It will be fine!!

But, once these URL I uploaded…
these dead space will be appear right and bottom… OMG…

I put my html source like this…

meta name=“twitter:player:width” content=“350”
meta name=“twitter:player:height” content=“196”

twitter:player:width
and
twitter:player:height
has problems…?
(my game size is same sizes…)

Should i change width and height parameter?

Please give me some advice. thank you.
